The EEC0381B3-000U-G99 from SUNON addresses cooling needs in industrial equipment. As a DC brushless axial fan, it creates a defined inlet-to-outlet route across the thermal load.
The SUNON product series carries RoHS compliance and recognized safety approvals; buyers should confirm the approval marks for this exact suffix and target market. Acoustic performance depends on the enclosure and operating point; low-turbulence integration helps avoid additional airflow noise.
OEM teams specifying EEC0381B3-000U-G99 should check airflow direction and complete system-resistance review before ordering. A documented interface review helps purchasing teams control fit, cooling continuity and replacement planning. Verify orientation so heated air does not recirculate through the inlet.
The listed speed is 2100 rpm. Confirm frequency, control method, and duty point for the installed system.
Verify supply, wiring, obstructions, impeller movement, and protection status. Use the model datasheet before replacement or repair.
Yes. The worksheet lists up to 44.8 Pa; compare it with the system curve.
Review its 120 × 120 × 38 mm size, 158.1 m³/h airflow, 44.8 Pa pressure, system resistance, and available mounting space.
It is listed for telecom cabinets, base stations, and network equipment. Check dimensions, airflow, pressure, and the installation environment against the actual equipment.
